GPU - 9.1 -> 9.2
R7 370 - 155 -> 156
R9 280 - 195 -> 193
r9 290 - 295 -> 313
What's your settings for 290?
1050/1250, -i 8, modded 390X ROM, modded timings
1175mV core (just 69% ASIC) and 16.12.1 driver
Try the 16.10.1 or 16.9.2 drivers, 16.12.1 COST me 5-10% hashrate on every card I tried it on when I was testing it.
Tested only with 9.1 @ R7 370:
16.9.2 - 153
16.10.1 - 154
16.12.2 - 155
Which R7 370 are u using?
I am getting 147 average from each
Are you using modded rom for them?
It is MSI Gaming 4G, running at 1175/1500
And yes I modded the ROM, without modding it is about 15 H/s slower.
